Ahhh guys this is all curse language to me lol
EF 24-70mm f/2.8 L ?
28 - 210 ?
FF cameras and no FF?
Is there a place i can go to, to learn about different lenses and what each one actually does....?
I did some googling and some rounding up of some of my own previous research to respond. I'm learning this stuff, too; so it also helps me to bring some of this stuff together in a post. Hope it helps.
APS-C.
Trusty ol' Wikipedia:
http://en.wikipedia.org/wiki/APS-C
The above linked page has a nice little paragraph about EF-S lenses.
The take home from the above is that the sensors of these cameras are smaller than 35 mm standard film.
That means a narrower field of view...
...and a crop factor:

And this page, "Image sensor format," is a really nice one, as well:

FF on this thread, I'm sure folks are talking about
full frame DSLR cameras. Here's Wikipedia on full frame:

It sounds like you already have a T2i. Reading the threads and posts here on Indie Talk, it sure sounds like a great choice. FF DSLRs would be primo, but something like the Mark ii goes for almost three-grand...and that's just for starters. Anyway, you would be using EF lenses with one of those, not an EF-S.
Because I just saw this review of the T3i last night and really liked it, I'm just going to throw this out there. It really sells the video (and the still photography) capabilities of the T3i --and the T2i, as well, since we're told by many sources that they are essentially the same camera.

You asked for directions to good online information about lenses. Actually, Canon's own site is a good (and a pretty) source.

And I happen to like Ken Rockwell's site a lot.
